摘　　要：为了探究苯酚富集的危害,以小白菜为材料,用不同浓度(0、10、20、30、40、50、60mg·L^(-1))苯酚溶液浇灌小白菜幼苗,分析由此产生的各种生物学效应。结果表明:苯酚会抑制蛋白质的合成;低浓度苯酚溶液会刺激可溶性糖的合成,当苯酚溶液浓度为30mg·L^(-1)时最明显;苯酚能抑制核酸的合成,在浓度为30mg·L^(-1)时细胞内核酸含量明显降低;同样,苯酚也能够抑制叶绿素的合成,从而使小白菜光合作用减弱,从而表现出随着苯酚浓度的升高,小白菜幼苗株高逐渐降低。In order to explore the harm of phenol enrichment,taking the Chinese cabbage as the material,the seedlings were watered with phenol solution of different concentrations(0,10,20,30,40,50,60mg·L1),and the various biological effects were analyzed.The results showed that phenol solution could inhibit the synthesis of protein;low concentration of phenol solution can stimulate the synthesis of soluble sugar.When the concen-tration of phenol was30mg·L1,the effect was most obvious.The phenol can inhibit nucleic acid.When phenol concentration was30mg·L1,the inhibition was most obvious.In the same way,phenol also inhibits the synthe-sis of chlorophyll.Because of the decrease of photosynthesis,the seeding height of Chinese cabbage decreased gradually with the increase of phenol concentration.
